Abstract: A communication circuit includes: a first radio frequency (RF) chain configured to output and/or receive a signal of a first frequency band through an antenna port; a second RF chain configured to output and/or receive a signal of a second frequency band through the antenna port; and a switch comprising a first terminal electrically connected to the first RF chain, a second terminal electrically connected to the second RF chain, and a third terminal electrically connected to a ground. The switch is configured to operate in a first operation mode or a second operation mode. In the first operation mode, the first terminal is electrically connected to the second terminal. In the second operation mode, the first terminal is electrically connected to the third terminal.

Abstract: An operation method of an electronic device includes determining whether a first communication module based on a first radio access technology (RAT) and a second communication module based on a second RAT operate in a connected state; determining whether a. combination of a first band used by the first communication. module and a second band used by the second communication module is a combination causing interference; and if the combination of the first band and the second band is a combination causing interference, transmitting a. signal requesting to change one of the first band or the second band. The interference is caused by at least one transmission signal of the first RAT or at least one other signal derived from the at least one transmission signal.

Abstract: An electronic device is disclosed and may comprise: an amplifier for amplifying a signal; a filter circuit for filtering the amplified signal; a coupler for delivering a feedback signal with respect to the filtered signal; an antenna for radiating the filtered signal to the outside; and a communication circuit for generating the signal, wherein communication circuit: generates a signal, using designated information; delivers the generated signal to the amplifier; acquires, from the coupler, a first feedback signal and a second feedback signal with respect to signals amplified by the amplifier; and determines whether there is an error in a signal transmitted to an external apparatus, on the basis of the designated information, magnitude information of the first feedback signal, and frequency information of the second feedback signal. In addition, various embodiments recognized through the specification are possible.
